Viewing and Exploring Test Results
Depending on the selected node in the tree view of tests, the Test Runner displays information on the various levels. In the Test Runner, you can view statistics of the tests, navigate to stacktrace, show or hide successful tests, and more.
Use the Testing toolbar to control visual representation of the test results.
The Statistics tab shows information about the elapsed time and memory usage of each test.
To view statistics, click on the Testing toolbar to reveal the drop-down menu, and then click the Show Statistics check command.
The values displayed in the Statistics tab are not accurate and only give an approximate estimate of the test performance. For example, if a garbage collector works during the test run, the memory usage shown in the Statistics tab is wrong.
If a unit test contains string
assertEquals failures, the test runner provides the ability to view differences between the compared strings. Choose the on the context menu of the failed test that contains
assertEquals, and explore differences in the Differences viewer:
Viewing the results of previously run tests
The results of a test session can be saved in two ways:
- Click to have the results of the selected test saved in a file. In the Export Test Results that opens, specify the file to save the output in and the format in which the data will be saved. If you want to view the test results later, choose the XML format.
- IntelliJ IDEA keeps track of test sessions and saves test results in its internal memory. Click to view the test results that you previously saved in an XML file or the results that IntelliJ IDEA has kept in its internal history. The pop-up menu that opens shows a list of internally saved results of test sessions, each item is supplied with the name of the run configuration and a time stamp.
- To view the results of a testing session from the IntelliJ IDEA history, select the item with the suitable run configuration and time stamp.
- To load the previously exported results, choose Import from file and then choose the required XML file in the dialog box that opens.
